COMBINED MOTOR AND CUSF ID OR.

SPECIFICATION forming part of Letters Patent No. 685,069, dated October22, 1901.

Application filed December 3,1900. s mi No. 38,443. (NomudeL) To allwhom it mag concern:

Be it known that I, JOSEPH E. VAN Nos- TRAN, a citizen of the UnitedStates, residing at Canton, in the county of Stark and State of Ohio,have invented certain new and useful Improvements in a Combined Motorand Ouspidor; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theannexed drawings, making a part of this specification, and to thefigures of reference marked thereon, in which- Figure 1 is a perspectiveview showing the different parts properly connected. Fig. 2 is avertical longitudinal section. Fig. 3 is a transverse section on line 00m, Fig. 2. Fig. 1 is a section on line a a, Fig. 2. Fig. 5 is a verticalcross-section of inlet-valve chamber.

The present invention has relation to combined motor and cuspidorsdesigned for use in dentistry, and is to be attached to a dental chair.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawlngs.

In the accompanying drawings, 1 represents the main body, which isprovided with the chamber 2, which chamber is for the purpose of holdingthe motor-wheel 3, which m0- tor-wheel is securely mounted upon theshaft 4:, one end of which shaft is properly journaled to the plate 5and the other end to the cap 6, which cap is connected to the body 1 bymeans of suitable clamping-bolts 7.

The body 1 is provided with the inlet-passage 8, to which passage isconnected in the usual manner the supply-pipe 9, said supplypipe beingextended upward beyond the shaft 4 and at its top or upper end islocated the valve-seat 10, said Valve-seat being held in.

proper position by means of suitable screwthreads and is extended intothe chamber 2, terminating in a nozzle 11.

Directly above the valve 10 is located the waterchamber 12, throughwhich waterchamber extends the tube 13, said tube being extended throughthe water-chamber 12 and into the cuspidor 14:, as illustrated in Fig.2, said tube 13 being provided with the nozzle 15, by which arrangementWater is supplied to the cuspidor, as hereinafter described.

For the purpose of allowing water to reach the chamber 2 andcome intooperative contact with the water motor or wheel 3 the passages 16 areformed in the valve-seat 10 so that when the valve 17 is moved outwardit will open the passages 16 and permit the water to flow out of thenozzle 11, thereby imparting a rotary movement to the water motor orwheel 3, and when it is desired to out off the supply of water to themotor the valve 17 is closed; but owing to the valve-seat 10 beingformed of a size less than the passage 8 water is permitted to passaroundthe valve-seat 10 and enter the water-chamber 12 regardless of theposition of the valve 17, so that water can be supplied to the cuspidorregardless of the operation of the motorwheel 3, as hereinafterdescribed.

I prefer to have the water fed to the cuspidor by opening the valve 19,and additional water may be passed through the passage 16. For thepurpose of allowing Water to pass from the water-chamber 12 into tube 13the apertures 18 are provided and are located and formed in the tube 13,it being understood that any desired number of apertures, such as 18,may be employed. 7 When it is desired to allow water-to enter thecuspidor 13, the valve 19 is opened, which allows water to enter fromthe water-chamber 12 into the tube 13 and find its way to the nozzle 15.r In the drawings I have illustrated the cuspidor 14 formed integrallywith the body 1 and said body provided with a waste-passage 20, whichwaste-passage communicates with the waste-pipe 21, thereby allowing thecontents of the cuspidor 1st to be removed through the same pipe thatdrains or carries off the Water after it has acted upon the motor 3.

For the purpose of preventing the water from accumulating in the chamber2, and thereby interfering with the rotary movement of the motor-wheel3, the waste-passage 20 opens into the chamber 2 for considerabledistance, and, as shown, said opening extends from the point 22 to thepoint 23, so that an additional or extending waste-chamber is providedor formed.

The cuspidor 14 is provided with the removable tube 24, which isextended downward into the passage 20, said tube being provided with theperforated catch-basin 25, said catch-basin being for the purpose ofreceiving and holding the fluid that may find its way into the cuspidor.

The bottom or under side of the cuspidor 14 is provided with the ridge26, upon the outer periphery of which are located the grooves 27, saidgrooves being for the purpose of holding a certain quantity at all timeswithin the cuspidor.

For the purpose of supporting the motor and cuspidor in proper positionthe rod or bar 28 is provided and is connected to a dental chair, andupon which rod the motor-frame and cuspidor are clamped by means ofsetscrews 29, said set-screws being located in the arms 30, said armsbeing provided with apertures through which the rod or bar 28 passes.

To the shaft 4 of the motor-wheel 3 is connected the flexible shaft 31,said flexible shaft being connected in the usual manner and its free orouter end so constructed that tools of various kinds can be attached,adescription of which is unnecessary, inasmuch as that particular partdoes not enter into the present invention.

For the purpose of removing the saliva from the mouth of the patient thepipe 32 is provided and has attached thereto an ordinary mouthpiece,(not herein shown,) and for the purpose of conveying the saliva to thecuspidor 14 the pipe 33 is connected to the tube 13 in front of thevalve 19, and for the purpose of providing a suction a chamber 34,formed in the pipe 13, is larger than the nozzle 35, which nozzle leadsinto the chamber 34, as illustrated in Fig. 2.

For the purpose of providing a means for supplying fuel-water for anypurpose the pipe 36 leads from the water-chamber 2 and is provided withan ordinary cut-off, such as 37.

For the purpose of preventing any splashing the cuspidor 14: is providedwith the inturned splashing flange 38, which splashflange is located andarranged at the upper part of the cuspidor.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A body provided with a chamber having located therein a motor-wheelfixed to a shaft, an inlet-passage located at one side of the chambercontaining the motor-wheel, a valveseat located at the upper end of saidinletpassage extended into the motor-chamber, a water-chamber locatedabove the valve-seat, passages communicating with the inlet-passages andthe valve located in the valve-seat, a tube located in the water-chamberand provided with apertures and a valve said tube extended into thecuspidor and the cuspidor located as described and waste-passagesleading from the cuspidor and the motor-chamber, substantially as andfor the purpose specified.

2. In a combined motor and cuspidor, a frame, a cuspidor fixed thereto,a chamber provided witha motor-wheel, an inlet-passage located at oneside of the motor-wheel chamber, a valve and its seat located at theupper end of the inlet-passage, a water-chamber located above the valveand its seat, said waterchamber provided with a tube havingperforations, aud a valve, said tube extended into the cuspidor, aWaste-passage communicating with the waste-passage from themotor-chamber, and an opening located between the cuspidor waste-passageand the motor-chamber waste-passage, substantially as and for thepurpose specified.

3. In a combined motor and cuspidor the combination of a body providedwith a motorchamber, a motor located in said chamber and aninlet-passage located at one side of the motor-chamber, a water-chamberlocated at the upper end of the inlet-passage, a pipe located in thewater-chamber said pipe connected in front of the valve located in saidpipe, and a nozzle extended into the cuspidor all arranged,substantially as and for the purpose specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

JOSEPH E. VAN NOSTRAN.
